The objective lens features a sextuplet air-spaced APO design and includes two pieces of ED glass, providing excellent correction of chromatic aberration. Specially optimized for a strophotography. Compared to FMA180, FMA180 pro adds a finder base and a 360° rotator. The focuser is designed as internal focusing which promotes its stability and ensures its performance in use as a delicate, high-quality, and compact astrograph. The FMA180 pro comes with an M48 adapter at the rear end, and the back focus is the standard 55mm. The multifunctional base can not only be used for astrophotography but also be mounted onto other telescopes' finder bases as a finder scope after the Vixen dovetail plate is detached. In a word, FMA180 pro is a compact astrograph for astrophotography with more integrated functions and a more dedicated design.
